Abstract
Techniques for per-channel image intensity correction includes linear interpolation of each channel of spectral data to generate corrected spectral data.
Claims20
A method of performing per channel image intensity correction comprising:
- receiving spectral data for a given image;
- applying a general two-parameter spline to each channel of the spectral data to generate corrected spectral data for the given image;
- and
- outputting the corrected spectral data for the given image.
1 more element
An imaging system comprising:
- one or more lenses;
- one or more image sensor arrays for measuring spectral data for the given image focused on the one or more image sensor arrays by the one or more lenses;
- a general two-parameter spline for generating corrected spectral data for each channel of the spectral data of the given image.
